Hello! My family and I recently passed through the Icelandair JFK Terminal and we had a pleasant and smooth time. The check-in was swift, and the attendants were professional and friendly, ensuring we had all our needs met. The terminal was clean, organized, and there was ample seating, which ensured waiting for the flight was not uncomfortable. We also liked the food and charging stations, which were quite handy. Boarding was smooth, and everything was on schedule. In general, the Icelandair made our trip hassle-free, and I strongly recommend it for an excellent travel experience!
